General Development Discussion / Re: What more can/should we do with ML?

« on: November 28, 2018, 07:09:13 PM »

No offense but 2) reminds me of a CEO asking dev team for "a stable alpha" for CeBIT. No joking. Happened to us (company < 50 employees). Techs went silent and nobody dared to speak up.

There is no such thing as "bug free software". In theory: Yes, within strict limitations. In real life applications: Nope, not gonna happen.
This doesn't imply getting rid off known bugs is useless (quite on the contrary) but there are limits what programmers can do and achieve. No matter how good and motivated they are.

If I remember correctly there was a remark by a1ex about releasing "stable v2.3" to be a mistake. Maybe he wants to share more details about this here. Can think of a reason but who am I to tell?

- PTP: that USB cable feels way too flimsy;

Available in IP67, too: https://www.phoenixcontact.com/assets/images_ed/global/web_content/pic_con_a_0051384_int.jpg

Industry: Let's create a standard interface without locking ability for easy access and removal.
Industry, too: Hey, let's screw it.
Industry: WTF?

I'm not sure about the merits of this thread. Kind of weird to discuss ML development tactic/strategy/roadmap without (core) devs participating ...
Anyway, let's dive into season spirit and make a wishlist.


Dear Santa,

I think this one is already on the to-do-list
- Button handling. Those Toshiba TX19A43CD and FD processors needs to be cracked to get rid of some feature hickups. Mixing up silent pics, intervalometer, advanced bracketing... Permanent DOF button would be fine for silent pic and focus stacking.

Minor thing
- Sound recorder. Con: Today everyone (almost) has a smartphone able to take notes of all sorts.

Big, big wish:
- ML via PTP. All of it!
Not a new wish. Remote controlling ML via smartphone/PC/Raspberry and derivates, maybe Arduino. For drone riders, remote locations (sports), and some studio applications it would make a big difference.
Not sure if (and how) it may interfere with ItsMeLenny's wish.


Your naughty boy
Walter

Best using 2 cards. One for ML and an obsolete one for Canon firmware.
Format both cards.
Use "obsolete" to downgrade to Canon firmware 1.0.5.
Copy ML for 1.0.5 to "ML card" and install ML on cam. Remove card.
Take "obsolete" and upgrade cam to Canon firmware 1.0.6.
Take "ML card" and copy files for ML (for 1.0.6) to card. Overwrite all files.

Done.

Actually there are 2 versions named "Samsung EVO plus"

old (slow): MB-MC128DA/EU
new (fast): MB-MC128GA/EU

The new one replaces "Samsung EVO pro" and is in fact quite fast.
Make sure to get the newer model.

Camera-specific discussion / Re: Canon 7D Mark I

« on: November 24, 2018, 12:22:47 PM »

but when I do the camera, it reverts to FAT32. Is that normal? Are we able to use the 7D with an exFAT formatted card?

https://www.magiclantern.fm/forum/index.php?topic=23064.msg208567#msg208567

but apparently ML kept recording til I hit stop, but my card wrote only the 4GB limit. So now I'm stuck with incomplete interviews.

Please check for files <Filename>.M00, M01, ... on card.
MLV recording on 7D uses file chunks up to file system limit.

If they are not there, please respond with build number, modules used.

General Help Q&A / Re: Canon 7D Does ML remove the 24' video recording limit ?

« on: November 23, 2018, 08:51:37 PM »

ML does not fix 7D's file system limitation: No ExFAT support. File size limit is 4 GB with or without ML. Canon decided to implement a "not that much sophisticated" file handling within this cam (and other Digic 4 cams), too (as you know already). Reaching 4 GB means: Stop recording and restart it. Therefore maximum recording time depends on video resolution.
ML can automate movie restart in native H.264 mode (= MOV recording). You will loose some frames during transistion, though.
BTW: Digic 5 cams do support ExFAT and will stop at 29:59 only. Fun fact: Recording exceeding 4GB will be splitt into file chunks each up to 4 GB! I suppose it is because compatibility with FAT32 devices.

ML can do seamless recording > 29:59 in RAW mode. Only limit: card size, battery and - sometimes - temperature.
Looks like a solution ... but there is a trade off, a serious one: Bandwidth. Uncropped 1728x972 in 24 fps with 14 bit depth will eat up around 67 MByte/s. Needs a fast card and a big one. Do the math ...
Cropping is available (=reduced data rate) but will use a smaller active sensor area  -> reduced FOV.

For other cams there are experimental builds offering reduced bit depth and lossless compression. 7D development is hampered by 7D's dual processor design ...

Oh, and there is HDMI recording, of course. Haven't tested if some of the latest developer wizardry (HDMI without hickups at 29:59) is working for 7D, too.

Raw Video / Re: Scandisk 128GB CF card 160MBs/sec only records 1920 HD

« on: November 21, 2018, 04:48:20 PM »

With uncompressed 14-bit RAW this is about the cam's limitation.
Vertical pixels x horizontal pixels x bit depth x fps / 8 = bandwidth needed
1920 x 1080 x 14 x 24 / 8 -> 87091200 bit/s -> 83.1 MiByte/s

Load module bench.mo, restart cam, go to Debug -> Benchmarks -> Card benchmarks -> Quick R/W benchmark (1 min)
Result will tell you the maximum write rate your cam-card combination is able to do.
Now take into consideration there is some computing overhead during recording. Thus "real life" numbers will be lower.

If you want higher resolutions may want to try lossless compression and/or lower bit depth.

Thank you for your feedback.
BTW: Those Canon firmware files linked in this site (=download pages) are not dmgs but exe or zip which will be expanded in macOS/OS X without troubles.
You may want to run MD5 or CRC32 check on those FIR files to see if there are any differences. File size doesn't really say that much about file integrity.

« on: November 20, 2018, 11:49:24 AM »

Test procedure:
- make sure crop mode is off
- restart the camera in photo mode
- "don't click me"
- check the printed message (number should be 1)
- switch to movie mode
- is crop mode enabled?

650D: Number is 1 and crop mode is enabled.

If you have a spare card with 32 GByte (or less) capacity:
- Format card in cardreader
- Remove and insert battery
- Insert card in cam and format again
- Copy Canon firmware file CCF11102.FIR to card.
- Insert card and battery and startup cam.
- Downgrade to 1.0.2.

Report back. And avoid crossposting.

Look into experimental build page. There are some major improvements not ready to be merged into main build. Yet.
And some pull requests waiting to be approved for main (=unified), too:

But agreed, we have seen busier days. Daily updates, sometimes even twice a day. I have no troubles with a more halcyon phase happening.

Unclear why mlv_rec.mo failed to load.
